[Power Supply Design Proposal Example] Adoption of Dropping Power Supply and High-Frequency Countermeasures

The dropper power supply is effective for using high-frequency circuits! Examples of achieving high-frequency countermeasures.

We received a request for the development of a power supply for an ultrasonic exploration device. Since high-frequency circuits are used in this power supply, it was necessary to design and develop it with high frequency in mind. When using high-frequency circuits, adopting a highly efficient switching power supply can lead to increased noise, which may result in malfunctions. Therefore, we adopted a dropper power supply. While the dropper power supply has lower efficiency compared to switching power supplies, it is low-noise and effective for use with high-frequency circuits. [Challenges] ■ Development of a power supply for an ultrasonic exploration device ■ Design and development must consider high frequency due to the use of high-frequency circuits ■ Adopting a highly efficient switching power supply can lead to increased noise and potential malfunctions *For more details, please refer to the related link page or feel free to contact us.
